New Zealand has been divided into 500 land environments. These have been defined by their unique climate, topography, and soils. The extent to which indigenous vegetation is represented in these land environments, and how that vegetation is formally protected, is described by threatened environment categories. These can be monitored to understand the effects of land cover change on indigenous biodiversity.
This dataset relates to the "Indigenous cover and protection in land environments" measure on the Environmental Indicators, Te taiao Aotearoa website.
